This was a combo with Meeker, route as follows: Ascent of Longs via Keyhole Route, "Clarks Arrow" traverse to Meeker via the Loft, traverse of Meeker Ridge and then a descent of Meeker‘s Iron Gates route back to Chasm Lake, trail out to trailhead. Keyhole route was still snowy, crampons and ice axe required from bottom of Trough as well as part of the descent to the loft.
